GKinetic Ltd. is a Co. Limerick based developer of a submerged tidal energy device composing of twin, multi-bladed, vertical axis turbines mounted either side of a tear drop shaped 'bluff body' that will be moored to the seabed. The full scale device is intended to be of the order of 500kW.
The concept has undergone staged development, in line with industry best practice. Previous testing has been undertaken at NUI Galway, the IFREMER flow tank facility at Boulonge-Dur-Mer in France and numerical modelling for design optimisation. Funding has previously secured through the EU FP7 MaRINET programme which included scientific evaluation and is an additional sign of technical quality. SEAI has awarded GKinetic Energy Ltd. a grant of €196,640 to conduct towing tests of a 1/10th scale version of the GKinetic Tidal Turbine System in Limerick Docks in order to assess the performance of the technology.
GKinetic recently won the Design category of the 2015 Sustainable Energy Award!
SEAI has approved funding of €2.3m to New Wave Technologies Ltd. (trading as Ocean Energy Ltd.) to design and build a full-scale version of their OE Buoy wave energy converter. The device will be deployed and tested at the US Navy Wave Energy Test Site (WETS) Hawaii. Successful completion of this project will confirm the sea-keeping and power production performance of the OE Buoy device.
The device is being co-funded by the US Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE). The award total is $5m, with additional operational support being provided by the US Navy.
The OE Buoy is a floating, oscillating water column type wave energy device, incorporating a bi-directional air turbine. The prototype that will be built for the Hawaii test will be 37m long, 17.m wide and have a draught of 9.5m. The device will weigh approximately 625 tonnes and will have a rated capacity of 500 kW. A key benefit of this device is that the power take off and electrical equipment are above the water line, improving the reliability of these critical components.
The technology has been developed through a rigorous series of tests at increasing scales and complexities, including tank tests at the Lir National Ocean Test Facility and quarter scale tests at the Galway Bay Wave Energy test site where it proved its ability to survive severe storm conditions.
